What is market capitalization?
Market capitalization (market cap) is the total market value of a publicly traded company’s outstanding shares, and is the most common way to gauge a company’s overall size.
The formula
Market Cap = Share Price × Shares Outstanding. Companies are commonly grouped into categories such as small-cap, mid-cap, and large-cap based on this figure, which affects how they’re treated by many index funds and investors.
